| Factors that do not affect speech reading ability | 1. education 2. IQ 3. duraton of deafness 4 age of offset 5. SES 5 . amount of practice |
| Factors that do affect speech reading ability | 1 gender 2 a ge -young people are better speech readers 3 motivation (weak) 4 linguistic and world knowledge |
| Difficulty of Speech Reading Tasks | Visibility of sounds 2. rapidity of speech 3. coarticulation 4. tallker variability 5.visemes |
| Visibility of Sounds | Lips sound -visible back sounds are not. SLower speech is easier but not too slow |
| Percentage of speech osund s that are visible | 40 |
| More visible sounds | f,v,l,p,b,m,w,th |
| Difficult sounds | k,g,n,t,d |
| Vowels | Are difficult to speech read but are longer in duration and have a higher frequency |
| Rapidity of Speech | Conversational speech is 150-200 wpm, 4-7 syllables per second or 15 phonemes per second |
| How much sound can the eye register? | 9-10 separate mouth movements per second a person can speak 10-15 |
| Coarticulation | Sounds that begin to look alike depending on phonetic and linguistic context - If you stress a word in a sentence then your mouth produces it differently In every talker a sound produced will look different |
| visemes | groups of phonemes that look alike on the face eg dj a nd j manner place- p/b/m |
| homophemes | words that look alike on the mouth Some words sound different but they look alike Some words sound close but they look diffrent |

| Speech reader/ Listener | People witrh greater amounts of residual hearing are better speech readers bc they have both visual and auditory cues. Type of hearing loss- conductive hearing loss just attenuated volume but sensorineural hearing loss will distort the signal |
| 2 approaches to speech reading training | analytic and synthatic |
| Analytic soeech reading trainig | develop vowel and consonant recognition increase patient s reliance on auditory cues while they are speechreadign both c=vision and hearing |
| synthetic | fora more advanced childe or adut - Start off with sentence discrimination for two phonemes and identify sentences speech read paragraphs and report on the meaning |
